Replace compile-time regex options with runtime options 
MENU_COLOR is now non-optional (at compile-time, you can still disable
menucolors at runtime).

The POSIX regular expression is consistently used
everywhere (previously, menucolors could use either the POSIX or the
GNU interface depending on a compile-time option, defaulting to GNU,
user sounds always used GNU, and everything else used POSIX).

MENU_COLOR_REGEX, MENU_COLOR_REGEX_POSIX, and USER_SOUNDS_REGEX have
been replaced by the new menucolor_regex and usersound_regex options.
menucolor_regex defaults to TRUE to maintain backwards compatibility
with old configs, but usersound_regex defaults to FALSE for
consistency with apexception_regex and and msgtype_regex.
